of .Massachusetts, insane, invented certain l improvements in ScourrngMachines, of which the following description, 1n connection withthe accompanying drawings, 1s 'a specification, like reference characters .on

the drawings indicating like parts in the several gures. v

This invention relates to abradlng machines and is herein illustrated as embodied in a machine for scouringa the margln of an ornamented top lift.

It is customary with some manufacturers to make use of top lifts which yare ornamented by having impressed upon thetread face thereof a design of some sort, said design being ordinarily imparted to the -top lift during the compressing operation.

' When, however, such a top lift has been incorporated into a shoe and it becomes necessary to scour vthe Jrow of slugs withv which a portion of the margin of the top lift of a finished shoe is loaded, a difficulty arises owing to the fact that the ordinary scouring wheel cannot be kept from contact with, and consequent marring of, the ornamented portion of the top lift.

Accordingly, the general object of the present invention consists in the provision of a machine whereby the marginal surface -of top ylifts or similar articles maybe scouredwitho'ut danger of injury to the remaining surface.y f -v In the illustrated embodiment of the invention a scouring disk ismounted upon a rotatable shaft, and a 'guardie provided for the edge of 'the heel so that a .marginal area of a predetermined width .only will be scoured, the arrangement of partsl insuring that the scouring niember shall not contact with the central'area ofthe lift.' Preferably the guard takes the for-moi a disk which is concentric with the scouring diskjand is rotatably mounted upon the shaft which actuates the scouring disk "so that said guard may remain stationary While a heel is being pressed against it.

These and other features of the invention including certain details of construction an connectionwith an illustrative machine and pointed out in theappended claims.

Referring now to the accompanying drawings,-Figure 1 is a perspective of a machine embodying the invention; Fig. 2 is a plan view of the upper tool with its shoe tion which it occupies during the scouring operation; .F ig. 3 is a section on the line 3- 3 of Fig.' 1, the heel of a shoe being shown in the position which it occupies support, a top lift being shown in the posiduring the scouring operation; and Fig. 4

sf. perspective showing an ornamented top Rising from a plate 1 which is fastened v by bolts .5 to a base 7 is `a standard 9 having two arms 11 and 13. At itsv forward end the arm l1 is formed with a yoke l5 having alined bearings 17 and 19 in which is rotatably mounted a shaft 21 which is provided with a pulley 23 around which passes a belt 25, said belt also passing over two guidelpulleys 27 fast to a shaft 29 andpbeing driven from any suitable. source of power. The lower end of the shaft 21 has a reduced portion 3l and a shoulder 33, the lower end of the reduced portion being threaded and carrying a nut I35 which bears' against Aa washer 37. "Above the washer is a support 39 which1may be of any suitable contour and is herein shown as disk-shaped. Above the support 39 is a disk 41 of yielding maferial, for example felt; and above the felt disk is a disk of abrasive material 43 herein shown as a piece of sandpaper. A clamping member 45 also shown asfa disk contacts with the abrasive disk, and a shim 47 is pliaced between the clamping disk 45 and the shoulder 33. With this construction, if a heel lift were placed with its edge against the clamping member. 45 as a guide and thepartS thus farde'scribed were rotated, there would be danger that the edge of the guide would burn the edge of the heel or otherwise mar yitsi appearance. In order to prevcombinations of parts will be described in and the nut 35. yWith this construction,

when a heell is placed in position to be scoured, the guard 4:9 remains stationary while the scouringtool revolves. A support 5'1 for the heel of the shoe is fast to a rod 5 3 which is slidable in a bracket 55, and carries lock nuts 57 bywhichit may be held in adjusted position, said position being preferably such that the plane of the supporting surface coincides with the plane of the responding partsof the lower mechanism..

In Fig. 4 there is shown at 400 an ornamented top lift having a receive the row` of slugs. In Fig. 3 there is shown at 300 a heel provided with such a top lift, said heel being in the position it p ness and the lift may said occupies during the scouring operation.

` In the operation of the machine, power having been applied to the( belt 25 and the supports 51 and. 151 having been properly adjusted, a heel isl presented to 'either tool after the manner shown in Figs. 2 and 3. Or if desired, the tools may be fitted with sandpaper of different degrees of coarsebe applied to the tools successively. The heads of the row of slugs may thus'be scoured withoutmarring the ornamented center of the top lift.

- Although the invention has been yset forth in connection with a particular machine, it should be understood that the invention is not limited in the scope of its application to tha-particular machine shownand described.

aving thus described my invention, what I claim as new and de sireto secure by Letters Patentof the United States is 1. A machine for scouringfthe marginal portion of a piece of stock, having, in com-I bination, an abradingtool comprising a supporting member .having a' flat face, an abrasive member, means for clamping said abrasivemember to said supporting member, a guard/rotatable with respect to said abrasive member extending partially over said abrasiveimember and means for actuattoo " 2. A machine for 4scouring the marginal portion of a piece of stock, having an abrad-r ing tool provided with a flat abrading surface of circular outline and a ard rotatable independently of said too in combination with a work rest having its operative face in substantially the plane of the abrading surface of the tool.
